1. l-Cysteine was fed to larvae carrying both a suppressor-erupt and a suppressor-tumor system, to test its effect in combination with x-ray treatments and with supplementary l-tryptophan in the diet. Cysteine itself had no effect on erupt eyes or on the incidence of melanotic tumors. 2. Fed before or after x-ray treatment, cysteine greatly reduced the radiation effect which blocks the action of the suppressor genes and thus engenders both tumors and erupt eyes. Cysteine was more effective in… Expand
